In its first two weeks on the market in North America, Scribblenauts sold 194,000 units, making it the third highest-selling DS title in September, behind Mario & Luigi and Kingdom Hearts sequels. That's 105,000 more copies than Grand Theft Auto: Chinatown Wars moved in its first month.We asked 5TH Cell creative director Jeremiah Slaczka if it met his expectations. "I didn't have any expectations," he told Joystiq. "I just hoped it'd do well. It's awesome for a completely new, original 3rd party IP on DS to do so well."Does this strong debut mean a sequel is guaranteed? "Way too early to tell that," Slaczka said. "We've only seen 2.5 weeks of sales." He told us that Drawn to Life, which went on to break a million worldwide, only sold 40,000 copies in its first month, with one more week of sales in that month.
